As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary.

[0065] In order to facilitate understanding of the embodiments of the present application, the following contents are first described.

[0066] In the embodiment of the present application, a physical random access channel transmission opportunity (PRACH transmission occasion) may also be referred to as a physical random access channel opportunity (PRACH Occasion), abbreviated as RO.

[0067] Optionally, multiple frequency division multiplexing (FDM) ROs may be configured at a time domain location for transmitting a PRACH. At a time, multiple ROs may be configured for FDM.

[0068] Optionally, there is an association between the RO and the SSB (SS / PBCH block, synchronization signal / physical broadcast channel block, sometimes simply referred to as SS block, synchronization signal block) actually sent. One SSB may be associated with multiple ROs, or multiple SSBs may be associated with one RO. When multiple SSBs are associated with one RO, different SSBs correspond to different preambles (Preamble). The base station can use different beams to send different SSBs, and the corresponding terminal sends the Preamble on the RO associated with the SSB. That is, there is also an association between the RO and the Preamble. For example, the Preamble can only be transmitted on the RO resources configured with specific parameters (such as the parameter PRACHConfigurationIndex), and the Preamble can only be transmitted on the frequency domain resources configured with specific parameters (such as the parameter prach-FDM).

[0069] In the embodiments of the present application, enhanced duplex, enhanced duplex, enhanced duplex mode, XDD, enhanced full duplex, enhanced full duplex mode, etc. may represent a concept, which may be expressed as supporting uplink subband transmission within a downlink time unit, and / or supporting downlink subband transmission on an uplink time unit, and / or supporting at least one of uplink subband transmission and downlink subband transmission on a flexible time unit, and / or uplink or downlink resource transmission on a set of at least two of the aforementioned three time units (i.e., downlink time unit, uplink time unit, and flexible time unit). The time unit includes but is not limited to a time slot, a symbol, a subband, etc.

[0070] In the embodiment of the present application, the RO may also include RO resources spanning at least two time units.

[0071] In the embodiment of the present application, the mapping of SSB to RO may also refer to the association between downlink signals and uplink signals / resources in a general sense, such as the mapping relationship between the channel state information reference signal (CSI-RS) and RO.

[0072] In the embodiments of the present application, Random Access Channel (RACH) Occasion (RO) or PRACH Occasion may refer to the time-frequency resources required for transmitting a PRACH sequence. RA or Random Access may refer to a random access process.

[0073] In the embodiment of the present application, SSB and SS / PBCH block can be used interchangeably, or can be other names, and can refer to any module that contains at least part of the synchronization signal, broadcast signal or other downlink broadcast signal.

[0074] In the embodiment of the present application, the PRACH resources may include PRACH time-frequency resources and / or PRACH sequences.

[0075] In the embodiment of the present application, a shared RO may refer to a PRACH sequence used for both a certain PRACH transmission and another PRACH transmission. A separate RO or a separately configured RO may refer to a PRACH occasion that is additionally configured only for different types of PRACH transmissions.

[0076] In the embodiment of the present application, PRACH repeated transmission refers to repeated transmission performed during each PRACH initial transmission or retransmission process.

[0077] In the embodiment of the present application, in order to support PRACH repetition transmission for one or more terminals supporting enhanced duplexing, and also considering PRACH repetition transmission for terminals that do not support enhanced duplexing, multiple sets of PRACH repetition transmission resources can be divided, such as forming multiple types of RO groups (i.e., RO groups). Different types of RO groups can be used for PRACH repetition transmission for terminals supporting different enhanced duplexing modes, or can be used for PRACH repetition transmission for terminals that support enhanced duplexing and terminals that do not support enhanced duplexing. The specific RO group type may depend on the network configuration. For example, as shown in Figure 2, RO groups can be divided into three types: one is case 1, which only includes ROs on uplink (UL) time units (such as uplink time slots, etc.), such as RO1, RO2, RO5 and RO6 in Figure 2, corresponding to four repeated transmissions of Rep.1, Rep.2, Rep.3 and Rep.4 respectively; another is case 2, which only includes ROs on downlink (DL) time units (such as the uplink subband of the downlink slot), such as RO3, RO4, RO5 and RO6 in Figure 2, corresponding to four repeated transmissions of Rep.1, Rep.2, Rep.3 and Rep.4 respectively; and the third is case 3, which includes ROs on UL time units (such as uplink slots, etc.) and ROs on DL time units (such as the uplink subband of the downlink slots, etc.), such as RO1, RO2, RO3 and RO4 in Figure 2, corresponding to four repeated transmissions of Rep.1, Rep.2, Rep.3 and Rep.4 respectively. For different types of RO groups, when they contain the same RO, some preamble resources need to be reserved for different instances.

[0078] The resource determination method, apparatus, terminal, and network-side equipment provided in the embodiments of the present application are described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0079] Please refer to FIG3 , which is a flowchart of a resource determination method provided in an embodiment of the present application. The method is executed by a terminal. As shown in FIG3 , the method includes the following steps:

[0080] Step 31: The terminal determines an RO group for repeated PRACH transmission according to the first information.

[0081] In an embodiment of the present application, the terminal may be in an idle state or an inactive state. To improve the flexibility of the terminal in using duplex mode in the idle or inactive state, an enhanced duplex mode may be configured in the idle or inactive state of the terminal, or dynamically configured during the random access phase. The enhanced duplex mode may be, but is not limited to, enhanced frequency division duplexing (FDD), enhanced time division duplexing (TDD), subbands non-overlapping full duplex (SBFD), etc.

[0082] Optionally, the first information includes but is not limited to at least one of the following:

[0083] The duplex capability of the terminal; for example, for a terminal supporting enhanced full-duplex capability, the RO group corresponding to case 1, case 2, or case 3 in Figure 2 may be used for PRACH repeated transmission; the specific association between the RO group type and terminals supporting different enhanced duplex and terminals not supporting enhanced duplex may depend on the network configuration;

[0084] Measurement metrics of downlink signals associated with different RO group types; here, the measurement metrics include but are not limited to Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), and functions between at least two of RSRP, RSRP, and SINR; for example, the terminal may select the corresponding RO group for PRACH repeated transmission based on the relative sizes of different synchronization signal-based RSRP (SS-RSRP) thresholds associated with different RO group types;

[0085] The preamble selected by the terminal; for example, the corresponding RO group can be selected for PRACH retransmission based on different types of preambles on the RO selected by the terminal for random access or downlink measurement; for example, as shown in Figure 2, if preamble X is selected on RO1, the RO group corresponding to case 3 can be selected for PRACH retransmission; or, if preamble Y is selected on RO1, the RO group corresponding to case 1 can be selected for PRACH retransmission;

[0086] The RO corresponding to the first PRACH transmission of the terminal; that is, the corresponding RO group is selected for PRACH repeated transmission according to the RO of the first PRACH transmission of the terminal, that is, a certain RO corresponds to a specific RO group / repeated transmission;

[0087] RO resources configured on uplink resources of enhanced duplex and uplink resources of non-enhanced duplex, or RO resources configured on uplink resources of non-enhanced duplex, or RO resources configured on uplink resources of enhanced duplex;

[0088] First configuration information related to the preamble on the RO;

[0089] The first mapping mode period or the second mapping mode period of the downlink signal to the RO; for example, the downlink signal may be an SSB, or a CSI-RS, or other signal used for downlink measurement and associated with PRACH transmission.

[0090] In some embodiments, for multiple types of RO groups, the terminal can select the corresponding RO group / RO group type based on at least one of the following: the terminal's duplex capability, the measurement metric value of the downlink signal associated with different RO group types, the preamble selected by the terminal, and the RO corresponding to the terminal's first PRACH transmission.

[0091] In some embodiments, for terminals that support one or more enhanced duplexing and terminals that do not support enhanced duplexing, the RO groups used for PRACH repeated transmission can be determined based on at least one of the following: RO resources configured on the uplink resources of enhanced duplexing and the uplink resources of non-enhanced duplexing, RO resources configured on the uplink resources of non-enhanced duplexing, and RO resources configured on the uplink resources of enhanced duplexing.

[0092] In some embodiments, for a terminal that does not support enhanced duplexing, the RO group for PRACH repeated transmission can be independently determined based solely on the RO resources configured on the uplink resources of non-enhanced duplexing. That is, for a terminal that does not support enhanced duplexing, the RO resources configured on the uplink resources of enhanced duplexing are ignored when determining the required RO group.

[0093] It should be noted that the enhanced duplex uplink resources may refer to transmission resources supporting uplink subbands in downlink time units, and / or transmission resources supporting downlink subbands in uplink time units, and / or transmission resources supporting at least one of uplink subband transmission and downlink subband transmission in flexible time units. This time unit may be a time slot, a symbol, etc. The non-enhanced duplex uplink resources refer to other time-frequency resources used for PRACH transmission.

[0094] The first mapping pattern period and the second mapping pattern period can be used to determine the time window of an RO group. For example, s (s is greater than 0) first mapping pattern periods or second mapping pattern periods constitute the time window of an RO group. Within this time window, the required RO group can then be determined using an overall RO group determination rule. For example, assuming the number of PRACH repetitions is N1, the overall RO group determination rule within the time window can be as follows: first, determine the starting RO of the first RO group, then determine the remaining N-1 ROs in the first RO group; then, sequentially determine the starting RO and its remaining ROs for the remaining RO groups, with the remaining N1-1 ROs in each RO group being ROs associated with the same SSB, the same relative frequency position, and the same associated preamble set as the starting RO. After the first RO group is determined, the determination of the remaining RO groups is related to whether a time offset is configured. It should be noted that this overall RO group determination rule can be agreed upon by protocol or preconfigured.

[0095] Through the solution of the embodiment of the present application, the terminal duplex capability (such as considering whether the terminal supports enhanced duplexing) and the measurement metric value of the downlink signal associated with different RO group types, the preamble code preamble selected by the terminal, the RO resources configured on the uplink resources of enhanced duplexing or non-enhanced duplexing, and the configuration information related to the preamble on the RO can be combined to determine the RO group for repeated PRACH transmission, thereby taking into account terminals that support and do not support enhanced duplexing and terminals that support different types of enhanced duplexing, thereby improving the robustness of PRACH transmission. In addition, by using this information to determine the RO group for repeated PRACH transmission, the network side device can detect PRACH on the RO resource corresponding to the capability of the terminal when detecting PRACH for a terminal that supports or does not support enhanced duplexing, or for a terminal that supports different types of enhanced duplexing, without having to detect on all RO resources, thereby reducing the complexity of network detection of PRACH to a certain extent.

[0096] Optionally, the resource determination method in the embodiment of the present application may further include:

[0097] The terminal receives second configuration information sent by the network-side device; the second configuration information is used to configure PRACH resources on the first RO, and the first RO is used for PRACH repeated transmission by terminals that support one or more enhanced duplexing and terminals that do not support enhanced duplexing. The PRACH resources are used for PRACH repeated transmission by terminals that do not support enhanced duplexing. That is, for a certain RO, when it is used for PRACH repeated transmission by terminals that support one or more enhanced duplexing and terminals that do not support enhanced duplexing, a portion of PRACH resources is reserved for PRACH repeated transmission by terminals that do not support enhanced duplexing. This PRACH resource is, for example, a PRACH sequence. In this way, PRACH repeated transmission of terminals that do not support enhanced duplexing can be guaranteed.

[0098] In an embodiment of the present application, for a terminal that does not support enhanced duplexing, that is, a terminal that only supports non-enhanced duplexing, if an RO group for repeated PRACH transmission is determined based on RO resources configured on uplink resources of enhanced duplexing and uplink resources of non-enhanced duplexing, at least one of the following may be performed:

[0099] 1) If the second RO in the RO group is on an uplink resource with enhanced duplexing, the terminal determines that the second RO is invalid, or determines that the second RO is not used for PRACH repeated transmission; that is, if a certain RO in the determined RO group is on an uplink resource with enhanced duplexing, the terminal determines / considers that the RO is invalid or that the RO is not used for PRACH repeated transmission;

[0100] 2) If the Xth RO in the RO group is on an uplink resource of enhanced duplexing, the terminal determines that the RO group is invalid, or determines that the RO group is not used for PRACH repeated transmission, where X is an integer greater than 0. For example, X is equal to 1, that is, if the first RO in the determined RO group is on an uplink resource of enhanced duplexing, the terminal determines / considers that the RO group is invalid or the RO group is not used for PRACH repeated transmission;

[0101] 3) If at least Y ROs in the RO group are on uplink resources of enhanced duplexing, the terminal determines that the RO group is invalid, or determines that the RO group is not used for PRACH repeated transmission, where Y is an integer greater than 0; for example, Y can be pre-configured or determined according to the number of repeated transmissions N, such as Y=N / 2;

[0102] 4) If the RO group includes ROs on uplink resources with enhanced duplexing and ROs on uplink resources with non-enhanced duplexing, the terminal uses different PRACH sequences for repeated PRACH transmissions. This allows the network to flexibly configure PRACH sequences for different terminal types on the two ROs.

[0103] In the embodiment of the present application, different types of preambles may be defined for PRACH transmission of terminals that do not support enhanced duplexing or for PRACH transmission of terminals that support one or more enhanced duplexing modes, so as to determine corresponding RO groups based on different types of preambles.

[0104] Optionally, this embodiment includes at least a first type of preamble and a second type of preamble, the first type of preamble is used for PRACH transmission of a terminal that does not support enhanced duplexing, and the second type of preamble is used for PRACH transmission of a terminal that supports one or more enhanced duplexing; or, the first type of preamble is used for PRACH transmission of a first type of terminal, the second type of preamble is used for PRACH transmission of a second type of terminal, the first type of terminal supports one or more enhanced duplexing, and the second type of terminal supports one or more enhanced duplexing different from the enhanced duplexing supported by the first type of terminal, that is, different types of preamble are used for PRACH transmission of terminals supporting different types of enhanced duplexing. The definitions of the first type of preamble and the second type of preamble can be interchangeable.

[0105] Optionally, the first configuration information related to the preamble on the RO may be used for at least one of the following:

[0106] -Configure the total number of first-class preambles on the RO;

[0107] -Configure the number of preambles for contention-based random access (CBRA) mapped to each SSB in the first type of preamble on the RO;

[0108] -Configure the total number of second-type preambles on the RO;

[0109] -Configure the starting preamble identifier of the second type of preamble on the RO (such as the starting preamble ID);

[0110] -Configure the number of preambles for CBRA mapped to each SSB in the second type of preamble on the RO;

[0111] Configure the interval between the set of first-class preambles and the set of second-class preambles. For example, after the last preamble of the first-class preamble, N preambles are reserved as the second-class preambles. That is, there is an offset between the first second-class preamble and the last first-class preamble.

[0112] -Configure the total number of preambles used for CBRA and contention-free random access (CFRA) in the first type of preamble on the RO; for example, the total number of preambles used for normal CBRA and CFRA in the first type of preamble on the RO can be configured; thus, the number of preambles used for other purposes such as system information request (SI request) in the first type of preamble is equal to the total number of first type preambles minus the total number of preambles used for CBRA and CFRA in the first type of preamble;

[0113] -Configure the total number of preambles for CBRA and CFRA in the second type of preamble on the RO; for example, the total number of preambles for normal CBRA and CFRA in the second type of preamble on the RO can be configured; thus, the number of preambles in the second type of preamble used for other purposes such as SI request is equal to the total number of second type preambles minus the total number of preambles for CBRA and CFRA in the second type of preamble.

[0114] Therefore, by configuring different types of preambles on the RO, the PRACH preambles used for PRACH repeated transmission of different types of terminals can be determined, and then the corresponding RO groups can be determined.

[0115] For example, there are a total of 64 preambles on each RO, as shown in Figure 4A. The total number of the first type of preamble (i.e., Preamble Type 1) is 28, which is mapped to 4 SSBs (i.e., SSB0, SSB1, SSB2, and SSB3 in Figure 4A). Each SSB used for CBRA is mapped to 5 preambles, and each SSB used for CFRA is mapped to 2 preambles. The total number of the second type of preamble (i.e., Preamble Type 2) is 28, which is also mapped to 4 SSBs (i.e., SSB0, SSB1, SSB2, and SSB3 in Figure 4A). Each SSB used for CBRA is mapped to 5 preambles, and each SSB used for CFRA is mapped to 2 preambles. There are 8 preambles between the two types of preambles, that is, the offset is 8 preambles.

[0116] For another example, there are a total of 64 preambles on each RO, as shown in Figure 4B. The total number of the first type of preamble (i.e., Preamble Type 1) is 32, of which the total number of preambles used for CBRA and CFRA is 28 and mapped to 4 SSBs (i.e., SSB0, SSB1, SSB2, and SSB3 in Figure 4B), each SSB used for CBRA is mapped to 5 preambles, and each SSB used for CFRA is mapped to 2 preambles; the total number of the second type of preamble (i.e., Preamble Type 2) is 28, of which the total number of preambles used for CBRA and CFRA is 28 and also mapped to 4 SSBs (i.e., SSB0, SSB1, SSB2, and SSB3 in Figure 4B), each SSB used for CBRA is mapped to 5 preambles, and each SSB used for CFRA is mapped to 2 preambles; both types of preambles reserve 4 preambles for other purposes (such as SI request).

[0117] Optionally, the preamble may be configured under each SSB. The first configuration information related to the preamble on the RO may be used for at least one of the following:

[0118] - Configure the total number of preambles on the RO under each SSB;

[0119] - The number of preambles for CBRA mapped to each SSB in the first type of preamble on the RO under each SSB;

[0120] -Configure the start preamble identifier of the second type of preamble on the RO mapped to the preamble for CBRA on each SSB under each SSB;

[0121] - The number of preambles for CBRA mapped to each SSB in the second type of preamble on the RO under each SSB;

[0122] -Configure the interval between the set of first-type preambles mapped to each SSB and the set of second-type preambles mapped to the same SSB under each SSB; for example, the preambles after the last preamble of the first-type preamble mapped to an SSB are reserved as the second-type preambles mapped to the SSB, that is, there is an offset between the first second-type preamble mapped to the same SSB and the last first-type preamble mapped to the SSB;

[0123] -Configure the total number of preambles for CBRA and CFRA on the RO under each SSB; for example, the total number of preambles for normal CBRA and CFRA on the RO can be configured under each SSB; thus, the number of preambles used for other purposes (such as SI request) is the total number of preambles minus the total number of preambles for CBRA and CFRA;

[0124] - The total number of preambles used for other purposes in the first type of preamble configured on the RO under each SSB; the other purposes are PRACH transmissions not used for CBRA and CFRA, such as PRACH transmissions sent for the terminal to request the network to send broadcast messages or activate certain downlink broadcast information, such as SI request;

[0125] - The total number of preambles for other purposes in the second type of preamble configured on the RO under each SSB; the other purposes are PRACH transmissions not used for CBRA and CFRA, such as PRACH transmissions sent for the terminal to request the network to send broadcast messages or activate certain downlink broadcast information, such as SI request;

[0126] -Configure the starting preamble identifier of the preamble used for other purposes in the second type of preamble on the RO under each SSB; the other purposes are PRACH transmissions not used for CBRA and CFRA, such as PRACH transmissions sent for the terminal to request the network to send broadcast messages or activate certain downlink broadcast information, such as SI request;

[0127] -Configure the number of preambles for CFRA mapped to each SSB in the first type of preamble on the RO under each SSB; the other uses are PRACH transmissions not used for CBRA and CFRA, such as PRACH transmissions sent for the terminal to request the network to send broadcast messages or activate certain downlink broadcast information, such as SI request;

[0128] -Configure the number of preambles for CFRA mapped to each SSB in the second type of preamble on the RO under each SSB; the other uses are PRACH transmissions not used for CBRA and CFRA, such as PRACH transmissions sent for the terminal to request the network to send broadcast messages or activate certain downlink broadcast information, such as SI request.

[0129] Therefore, by configuring different types of preambles on the RO, the PRACH preambles used for PRACH repeated transmission of different types of terminals can be determined, and then the corresponding RO groups can be determined.

[0130] For example, there are 64 preambles on each RO, as shown in Figure 4C. The total number of preambles used for normal CBRA and CFRA is 48, mapped to 2 SSBs (i.e., SSB0 and SSB1 in Figure 4C). Each SSB used for CBRA is mapped to 10 first-class preambles and 10 second-class preambles, and each SSB used for CFRA is mapped to 2 first-class preambles and 2 second-class preambles. The total number of preambles used for other purposes (such as SI request) is 16, also mapped to 2 SSBs (i.e., SSB0 and SSB1 in Figure 4C). Each SSB is mapped to 4 first-class preambles and 4 second-class preambles.

[0131] In an embodiment of the present application, under an enhanced duplex configuration, multiple RO types may appear, such as an RO on an uplink subband on a downlink time slot and an RO on an uplink time slot. At this time, the two types of RO may be the same set of PRACH configuration resources, and the downlink signal needs to be mapped to the RO together, or even if the two types of RO are independently configured resources, all related downlink signals may be mapped to the RO. At this time, in order to ensure that both types of RO can be mapped to the downlink signal, different mapping orders or methods may need to be used in different specific periods. This will change the mapping period of the downlink signal to the RO, and will also affect the determination period of the RO group. Based on this, the first mapping mode period and the second mapping mode period of the downlink signal to the RO are introduced in this embodiment to ensure that all downlink signals (such as SSB) can be mapped to the RO on the configured uplink resource.

[0132] Optionally, the first mapping mode period of the downlink signal to the RO may satisfy at least one of the following:

[0133] (1) The first mapping mode period includes multiple mapping periods, and at least two of the multiple mapping periods use different association orders or association methods for downlink signals to ROs; that is, within the first mapping mode, at least two mapping periods use different association orders or association methods for downlink signals to ROs; in this case, matching ROs can be selected according to actual needs to form an RO group;

[0134] (2) In one or more first mapping pattern periods, for each downlink signal associated with a specific index (such as an SSB index), there is at least one RO group, and the RO group is only related to uplink resources of non-enhanced duplexing, or the RO group is determined as a resource for PRACH retransmission of a terminal that does not support enhanced duplexing; that is, based on this first mapping pattern period, the PRACH retransmission resource of the terminal that does not support enhanced duplexing can be determined;

[0135] (3) Within one or more first mapping pattern periods, for each downlink signal associated with a specific index (e.g., an SSB index), there is at least one RO group, and the RO group is associated with uplink resources of non-enhanced duplexing and uplink resources of enhanced duplexing, or the determination of the RO group is a determination of resources for PRACH retransmission of a terminal supporting enhanced duplexing; that is, based on this first mapping pattern period, the PRACH retransmission resources of the terminal supporting enhanced duplexing can be determined;

[0136] (4) Within one or more periods of the first mapping mode, there is at least one RO group associated with each downlink signal having a specific index (such as an SSB index), and the RO group is only related to the uplink resources of the enhanced duplex, or the RO group is determined as the resource determination for the PRACH repeated transmission of the terminal supporting the enhanced duplex; that is, based on this first mapping mode period, the PRACH repeated transmission resources of the terminal supporting the enhanced duplex can be determined.

[0137] Optionally, the second mapping mode period of the downlink signal to the RO may satisfy at least one of the following:

[0138] (a) At least two of the second mapping mode periods use different downlink signal-to-RO association orders or association methods; that is, different downlink signal-to-RO association orders or association methods are used between different second mapping modes; in this case, matching ROs can be selected according to actual needs to form an RO group;

[0139] (b) within one or more N times the second mapping pattern period, for each downlink signal associated with a specific index (e.g., an SSB index), there is at least one RO group, and the RO group is only related to uplink resources of non-enhanced duplexing, or the RO group is determined as resources for PRACH retransmission of terminals that do not support enhanced duplexing; N is an integer greater than 1; that is, based on this second mapping pattern period, PRACH retransmission resources for terminals that do not support enhanced duplexing can be determined;

[0140] (c) within one or more M times the second mapping pattern period, for each downlink signal associated with a specific index (e.g., an SSB index), there is at least one RO group, and the RO group is associated with uplink resources of non-enhanced duplexing and uplink resources of enhanced duplexing, or the RO group is determined as resources for PRACH repetitive transmission of a terminal supporting enhanced duplexing; M is an integer greater than 1; that is, based on this second mapping pattern period, the PRACH repetitive transmission resources of the terminal supporting enhanced duplexing can be determined;

[0141] (d) Within one or more P times of the second mapping mode period, for each downlink signal associated with a specific index (such as an SSB index), there is at least one RO group, and the RO group is only related to the uplink resources of the enhanced duplex, or the RO group is determined as the resource for PRACH repeated transmission of the terminal supporting enhanced duplex; the P is an integer greater than 1; that is, based on this second mapping mode period, the PRACH repeated transmission resources of the terminal supporting enhanced duplex can be determined.

[0142] Optionally, the second mapping mode period may be any one of the following or a function of at least one of the following (that is, obtained based on at least one of the following operations):

[0143] Downlink signal to RO mapping period;

[0144] The association period of the downlink signal to the RO;

[0145] Enhanced duplex configuration cycle.

[0146] It should be noted that the downlink signal may be an SSB, or a CSI-RS, or other signal used for downlink measurement and associated with PRACH transmission.

[0147] Optionally, in order to reduce the complexity of implicitly determining the time window of the RO group, the determination window of the RO group can be directly configured through the network. The resource determination method in the embodiment of the present application may further include:

[0148] The terminal receives third configuration information sent by the network side device; the third configuration information is used to configure the time window of the RO group, the time window includes one or more first mapping mode periods, or the time window includes one or more second mapping mode periods.

[0149] In some embodiments, when RO groups of resources in multiple duplex configurations appear, the network device may configure a time window for determining the RO group, for example, through system messages, dedicated Radio Resource Control (RRC) signaling, or physical layer signaling.

[0150] Please refer to FIG5 , which is a flowchart of a configuration method provided in an embodiment of the present application. The method is performed by a network-side device. As shown in FIG5 , the method includes the following steps:

[0151] Step 51: The network-side device sends configuration information to the terminal.

[0152] In this embodiment of the present application, the configuration information may include at least one of the following:

[0153] First configuration information related to the preamble on the RO;

[0154] Second configuration information is used to configure PRACH resources on a first RO, where the first RO is used for PRACH repeated transmission by terminals that support one or more enhanced duplexing and terminals that do not support enhanced duplexing, and the PRACH resources are used for PRACH repeated transmission by terminals that do not support enhanced duplexing; that is, for a certain RO, when it is used for PRACH repeated transmission by terminals that support one or more enhanced duplexing and terminals that do not support enhanced duplexing, a portion of PRACH resources is reserved for PRACH repeated transmission by terminals that do not support enhanced duplexing;

[0155] The third configuration information is used to configure a time window of the RO group, where the time window includes one or more first mapping mode periods of downlink signals to the RO, or the time window includes one or more second mapping mode periods of downlink signals to the RO;

[0156] The fourth configuration information is used to configure RO resources on uplink resources of enhanced duplex or uplink resources of non-enhanced duplex.

[0157] Therefore, with the help of the configuration of the network-side equipment, the terminal can determine the RO group for PRACH repeated transmission based on its own duplex capability (i.e., considering whether it supports enhanced duplexing) and the measurement metric values ​​of downlink signals associated with different RO group types, the preamble code selected by the terminal, the RO resources configured on the uplink resources of enhanced duplexing or non-enhanced duplexing, and the configuration information related to the preamble on the RO. This takes into account terminals that support and do not support enhanced duplexing, as well as terminals that support different types of enhanced duplexing, thereby improving the robustness of PRACH transmission.

[0164] Configure the interval between the set of first-class preambles and the set of second-class preambles. For example, after the last preamble of the first-class preamble, N preambles are reserved as the second-class preambles. That is, there is an offset between the first second-class preamble and the last first-class preamble.

[0165] -Configure the total number of preambles used for CBRA and contention-free random access (CFRA) in the first type of preamble on the RO; for example, the total number of preambles used for normal CBRA and CFRA in the first type of preamble on the RO can be configured; thus, the number of preambles used for other purposes such as system information request (SI request) in the first type of preamble is equal to the total number of first type preambles minus the total number of preambles used for CBRA and CFRA in the first type of preamble;

[0166] -Configure the total number of preambles for CBRA and CFRA in the second type of preamble on the RO; for example, the total number of preambles for normal CBRA and CFRA in the second type of preamble on the RO can be configured; thus, the number of preambles in the second type of preamble used for other purposes such as SI request is equal to the total number of second type preambles minus the total number of preambles for CBRA and CFRA in the second type of preamble.
